  • Aiming at the problem that the existing human behavior recognition algorithm cannot fully utilize the multi-level spatio-temporal information of the network, a human behavior recognition algorithm based on a dense three-dimensional residual network is proposed. First, the proposed algorithm uses a dense block of three-dimensional residuals as the basic module of the network. The module extracts the hierarchical features of human behavior through densely connected convolutional layers; Secondly, the local feature aggregation adaptive method is used to learn the local dense features of human behavior; Then, the residual connection module is applied to promote the flow of feature information and reduced the difficulty of training; Finally, the multi-layer local feature extraction of the network is realized by cascading multiple three-dimensional residual dense blocks, and use the global feature aggregation adaptive method to learn the features of all network layers to realize human behavior recognition. A large number of experimental results on benchmark datasets KTH show that the recognition rate (top-l accuracy) of the proposed algorithm reaches 93.52%. Compared with the three-dimensional convolutional neural network (C3D) algorithm, it has improved by 3.93 percentage points. The proposed algorithm framework has good robustness and transfer learning ability, and can effectively handle a variety of video behavior recognition tasks.

  • The purpose of this study was to investigate the effect of parenting processes(parental support, monitoring, communication about sexuality) on college students' sexual attitudes and sexual behaviors. For this purpose, a survey was conducted using self-administered questionnaires with 361 college students. The results showed that both sexual attitudes and sexual behaviors were different according to sex, age, and dating period. In addition, sexual attitudes of males were correlated with father's support, mother's support and monitoring of parenting processes. It also found that the direct sexual behaviors were correlated with mother's support. Finally, results of multiple regression analysis showed that sex, parents' support, monitoring and communication about sexuality influenced sexual attitudes. Sex and parents' support had indirect influence on sexual behaviors. Experience of dating and communication about sex had direct influence on sexual behavior.

  • As the ultimate goal of the Aeronautical communication is delivery of information, it is essential to communicate via accurate use of language; there are possibilities of errors occurring as the exchange of information between pilot and air traffic controller is conducted through radio communication. Especially, there are frequently reported errors in radio communication in the event that two or more aircrafts using similar call-signs are operated in one sector. In this paper, a list of errors, which can possibly caused by air traffic controllers when controlling airplanes using similar call-signs, was derived through preceding researches and theories related to similar call-signs and human errors. Based on this list, an experiment was conducted on 52 air traffic controllers working at "J" international airport. For this experiment, ATC2K which is a simulated approach control radar developed in Korea, was used; and a regression formula was derived by analyzing the quantity of frequency change in error occurrence when controlling two or more airplanes using similar call-signs base on a premeditated scenario.The data presented in this research has useful findings and concepts for understanding the errors that can possibly occur while controlling airplanes using similar call-signs.

  • 최근의 스마트폰의 등장으로 기기간의 역기능들이 속속히 드러나고 있다. 대표적으로 컴퓨터에 의한 정보통신의 역기능을 그 예로 들 수 있다. 또한 갈수록 고도화 되어가는 사이버를 겨냥한 해킹 위협은 그 피해와 파괴력이 점점 확산되고 있어 국가적인 위기로까지 고려해 보아야 할 상황에 이르렀다. 이러한 상황에서 정보기술의 범죄는 사회적인 문제로 볼 수 있다. 인터넷의 발달로 스마트해진 기기뿐 아니라 선박, 비행기, 건물 그리고 자동차에도 디지털화된 기술이 많이 추가됨으로써 해커들의 공격이 가능해 지고 있다. 인간과 인간, 기기들간, 인간과 기기간 모두 사회적 위기로 볼 수 있다. 본 논문에서는 이와 같은 문제를 연구하고자 한다.

  • As the information-oriented society makes progress, the role of Image has much influence on human being in space as a medium for information delivery and a means of artistic communication. These influences are appeared as expressional characteristics of the image such as the reproducibility of reality and unreality in the real world, the synchrony of expression of time, visual formality, a sign and the transmission of moaning. For these, the investigator examined the meaning of image in aspace, taking into consideration of the interrelationship of image, space, and human being. As study findings show, the expressional characteristics of image in space have such visual effects as a space in which pictorial formality and object exists, in which the mutual understanding of communication exists, and that realizes immaterial membrane in the aspect of time and space, according to the electronic light, color, and formation of the image media. In addition, it become clear that the characteristic could be staged on various circumstances by constructing the relationship between an object and a point of time interactively with bidirectional communication through combining technology and art. This suggests that the image develops as the form of sensory communication via interacting of space and human being.

  • It has been focused on that the major reasons of aircraft accidents resulted not from human error but from the failure of teamwork or communication in 1980's. Such opinions were suggested in the workshop, so called, "Resource Management on the Flight Deck" by NASA in 1979. The researchers agreed the fact the source of human error was originated from the failure in teamwork, communication or even in leadership of captain. Due to the rapid development of aircraft technologies, the reasons for aircraft accident could be easily found out. According to the analysis results of the technology, most of reasons for the accident might directly be connected not to human error or stick-Rudder skill but to situational awareness, communication, leadership or decision making in the aircraft. This paper has tried to research empirically the satisfaction of flight crews who have gone thorugh CRM training in the commercial airline. Based on the quantitative scale by J. Ford et al. (2014), this paper has proved which characteristics of CRM training has a positive impact on the overall satisfaction of CRM training. It was proven that the teamwork and decision making programs among CRM training have a major effect to the satisfaction level of flight crews.

  • This paper presents a low-power and lightweight human body communication (HBC) receiver with an embedded dummy electrode for improved signal acquisition. The clock data recovery (CDR) circuit in the receiver operates with a low supply voltage and utilizes a clock phase inversion scheme. The receiver is equipped with a main electrode and dummy electrode that strengthen the capacitive-coupled signal at the receiver frontend. The receiver CDR circuit exploits a clock inversion scheme to allow 0.9-V operation while achieving a shorter lock time than at 3.3-V operation. In experiments, a receiver chip fabricated using 130-nm complementary metal-oxide-semiconductor technology was demonstrated to successfully receive the transmitted signal when the transmitter and receiver are placed separately on each hand of the user while consuming only 4.98 mW at a 0.9-V supply voltage.

  • 부부간 의사소통은 결혼 기간이 축적될수록 '공유된 경험세계'가 상대적으로 많은 반면 '친밀성'으로 인해 다양한 의사소통 문제들이 창출되는 산실이기도 하다. 따라서 부부간 의사소통은 표면적으로 매우 용이한 의사 소통 상황으로 비추어질 수 있지만 심층적으로 살펴보면 다양한 대인 커뮤니케이션(interpersonal communication)의 문제가 산재해 있음을 볼 수 있다. 이 연구는 한국사회의 부부간 의사소통 행태를 각 세대별로 나누어 그 특성을 탐색해보고, 결혼생활이 축적됨에 따라 나타날 수 있는 부부간 의사소통 행태의 변화 추이를 살펴보는데 중점을 두었다. 이러한 연구목적을 달성하기 위하여 20대, 30대, 40대, 50대 부부, 즉 연령 동기자 그룹을 대상으로 대인 커뮤니케이션과정의 5가지 차원-개방적 태도 차원, 문제 해결 차원, 의사 표현 차원, 경청(傾聽) 차원, 피드백 차원에서 설문조사를 진행하여 그 결과를 분석해보고자 하였다. 분석 결과 부부간 의사소통 행위의 특성이 각 세대별로 파악 되었으며, 다시 의사 종단 분석을 통하여 개방적 태도 차원, 문제 해결 차원, 의사 표현 차원, 경청 차원, 피드백 차원의 부부간 의사소통 행위가 변천하는 과정을 추적해볼 수 있었다.

  • 이 연구는 이동전화에 대한 채널 정향, 면 대 면 커뮤니케이션의 회피 등 이용자들의 인적 속성이 이동전화 이용의 다양성, 이동전화의 적합성 거부감 그리고 이동전화를 통한 커뮤니케이션 네트워크에 미치는 영향을 살펴보려는 목적에서 출발했다. 대학생과 40대 이상의 그들의 가족들로 구성된 피조사자들을 대상으로 설문조사한 바를 분석한 결과, 응답자들은 이동전화에 대한 사회적 실재감과 친밀도가 높을수록 이동전화 서비스를 더욱 다양하게 이용하고 대인커뮤니케이션 매체로서 더욱 긍정적으로 평가하며, 이동전화에 대한 거부감도 더 작은 것으로 밝혀졌다. 아울러 면 대 면 커뮤니케이션이 원활하지 못한 사림들은 이동전화를 통한 대인커뮤니케이션 네트워크의 폭과 이동전화 이용량도 상대적으로 제한돼 있음을 알 수 있었다. 즉시성, 직접성, 이동성, 접근용이성 등 이동전화의 여러 가지 기술적 강점에도 불구하고 면 대 면 커뮤니케이션이 원만하지 못한 이용자들은 새로운 인간관계의 형성보다는 그들의 편협한 대인관계의 유지 강화에 이동전화를 주로 이용하고 있음을 이 연구결과는 보여주고 있다.
